Problems solved by technology

[0004] Most of the current chewing robots only simulate and reproduce chewing movements, but the accuracy and accuracy of their simulated movements cannot be guaranteed. The common types of chewing movements include alternating bilateral chewing, simultaneous bilateral chewing, left chewing and right chewing , most of the current chewing robots cannot truly reproduce the movement and biomechanical characteristics of the lower jaw due to their own design flaws

Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments.

[0029] Such as figure 1 As shown, a bionic mastication mechanism with a double Hooke hinge includes a maxilla model 1, a mandible model 2, two bionic temporomandibular joints 3 and a simulation muscle group 4, and the maxilla model 1 is respectively arranged on the mandible Two groups of bionic temporomandibular joints 3 on both sides of the bone model 2 are connected with the mandible model 2;

[0030] In this example, the 1:1 skull model composed of the maxilla model 1 and the mandible model 2 was processed based on the CT scan of the skull of a healthy adult, as shown in Figure 4 and Figure 5 As shown, the maxilla model 1 and the mandible model 2 obtained after processing are respectively; the maxilla model 1 is fixed, and the mandible model 2 can move around two bionic temporomandibular joints 3 driven by the simulated muscle ...

Abstract

The invention discloses a bionic chewing motion mechanism with double Hooker hinges. The mechanism comprises an upper jaw bone model, a lower jaw bone model, two bionic temporal-mandibular joints anda bionic muscle set; the upper jaw bone model is connected with the lower jaw bone model through two sets of bionic temporal-mandibular joints arranged on two sides of the lower jaw bone model; four sets of double Hooker hinge devices are arranged in the bionic temporal-mandibular joints for realizing free movement of the lower jaw bone model within six degrees of freedom; and the lower jaw bone model is driven through the bionic muscle set. The bionic motion device can be widely applied to such fields as lower jaw recovery, dental recovery, food character analysis and speech therapy.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, in particular to a bionic chewing motion mechanism with double Hooke hinges. Background technique [0002] The human masticatory system is composed of maxilla, mandible, masticatory muscles and temporomandibular joints; among them, the mandible can realize chewing movement under the action of masticatory muscles. [0003] The chewing robot can simulate the human jaw movement behavior and reproduce its biomechanical environment. The chewing robot has great application value and can be applied to the fields of jaw rehabilitation, dental rehabilitation, food texture analysis and speech therapy. It is a combination of mechanism, kinematics , dynamics, perception system, motion control and mechatronics and other technologies in one engineering science. [0004] Most of the current chewing robots only simulate and reproduce chewing movements, but the accuracy and accuracy of their simulated move...
